Case Study: Readwise achieves scalable AI-powered search with turbopuffer

Readwise - Customer Case Study

Readwise, a reading platform that helps users collect and revisit their books and articles, needed a way for users to search across their entire libraries. Other solutions like PostgreSQL and stuffing documents into LLM context windows were not scalable or cost-effective, and other vector databases were too expensive for their consumer business. This challenge inspired turbopuffer's creation.

turbopuffer provided a scalable and cost-effective unified solution for vector and full-text search. Readwise implemented it in less than a month, ingesting over 150 million vectors while keeping costs sustainable and allowing users with 100,000 highlights to onboard instantly. This enabled Readwise to confidently ship new AI features like "Chat with Highlights" and prepare to launch "Chat with Your Entire Library," powered by turbopuffer.
